Wating to hear how you drilled out the pockets for the rail????? I have a similar project and am interested to see how ya did it.
Here ya go:
I finally found some time to drill out the rest of the posts today.
To make each slot I drilled three 1.5" holes in line.
Once I finished drilling the set of posts I went back and flushed the drill bit curves with my chain saw. I plunged the saw through the hole on each side.
All of this
sounds time consuming, but in practice it only takes one minute per post if you line them up as I did. Plus, I like the look of these timbers a whole lot better than the bulky split rail fences they sell. These don't block your view nearly as much. Rub a coat of cedar color stain on them and they look gorgeous.
For the first section of fence I installed all of the posts before installing the rails, this turned out to be a mistake. I quickly learned doing it that way caused the posts to be slightly out of measurement and some rails fit where others were too long and needing trimming. On the next set of posts I'll install the rails on the ground and bury the posts with rails already installed. It'll be tougher getting the posts in, but the work will be over once they are.
As for the drill bit, I used an auger bit. It's important to note the archaic drill I'm using. That's because it is a high torque drill which spins the bit slower. These auger bits dig
really fast, putting way too much torque on even mid-range drills. I have a decent rigid hammer drill and it barely makes it through a post. I borrowed this one from a neighbor. It looks rough (and is rough), but nothing beats the torque it puts out.
As for the auger bit, be sure to keep the edge sharp using a diamond home, as any dullness at all will make the drill feel the pain. Plus, these landscape timbers are the center of the tree, so they are often sopping wet and hard as nails. I used all of the dry pieces for the rails in order to avoid them warping after slicing them, which means all of the holes were drilling in the heavy, wet ones. If you don't have a high torque drill, it may cost less to replace rails which warp than risk drilling into wet, heavy timbers and burn out your drill. Something to keep in mind.
I'll be installing the last sections tomorrow.
Cheers!
